The token associated with defunct crypto exchange FTX surged briefly Monday night after Sam Bankman-Fried, the founder and onetime CEO of the platform tweeted for the first time in two years.

Bankman-Fried, who was convicted on seven different counts of fraud and conspiracy in November 2023, is serving out a 25-year prison sentence. He’s currently detained in the Metropolitan Detention Center in Brooklyn as his lawyers work through an appeal of his conviction. Still, his account on X (formerly Twitter) posted a 10-tweet thread about layoffs, seemingly referencing Elon Musk’s push to have federal employees email their work activities from the past week or risk resignations.

«I have a lot of sympathy for [government] employees: I, too, have not checked my email for the past few (hundred) days,» his thread began. FTT, the token associated with FTX, briefly spiked from roughly $1.55 to $2.07 after his tweets before falling back to around $1.78, according to CoinGecko.

Bankman-Fried does not have direct access to sites like X or email, but can send messages through the Corrlinks system, which lets prisoners in the U.S. communicate with others, a person familiar confirmed.

It was not immediately clear who might be posting the tweets on Bankman-Fried’s behalf.

Over the weekend, Musk, who according to court documents is a special government employee, tweeted that federal employees would have to tell the Office of Personnel and Management what they did last week, with a non-response being considered a resignation. While some federal agency heads or other leaders told their employees not to respond, others said their employees should reply.

It’s another step in Musk’s efforts to lay off broad swaths of the federal workforce at the behest of U.S. President Donald Trump.

Bankman-Fried’s tweets referenced layoffs and detailed circumstances that might cause an employer to fire employees.

«It isn’t the employee’s fault, when that happens. It isn’t their fault if their employer doesn’t really know what to do with them, or doesn’t really have anyone to effectively manage them. It isn’t their fault if internal politics lead their department to lose its way,» the thread said.

After Bankman-Fried’s tweets, another X account claiming without evidence to be him linked a contract address, claiming he received a pardon from Trump and now works for DOGE, the government entity that may or may not be led by Elon Musk. The linked token saw some immediate trading volume, according to on-chain data. The new, seemingly fake account has a label saying «it is a government or multilateral organization account,» suggesting a government agency account may have been compromised and renamed.

Solana’s dominant automated market maker (AMM) Raydium hit back Monday on rumors that major volume driver Pump.Fun was preparing to launch its own AMM.

Abandoning Raydium whole hog would be a «strategic miscalculation» for the massively popular — and profitable — memecoin factory, core contributor InfraRAY said in a post on X. He cast doubt on the notion that Pump.Fun could replicate its success if it swaps Raydium out for in-house trading infrastructure.

Token investors dumped RAY en-masse this weekend after hawkeyed observers noticed Pump.Fun was apparently testing its own AMM, presumably with the intent to replace Raydium’s longstanding liquidity pools as its platform of choice. Such a move would shake up the economics of decentralized token trading on Solana.

Right now, Raydium, the chain’s largest AMM platform, captures trading fees generated by Pump.Fun memecoins that «graduated» from the launchpad to its own pools. The arrangement — in place since Pump.Fun’s earliest days — has been a financial boon for Raydium

But it also leaves Pump.Fun out of the long-term upside of the tokens its users create. That’s not to say it’s making nothing: Pump.Fun has amassed half a billion dollars on the fees it collects from early-stage token launches, one of crypto’s grandest warchest.

Raydium is currently generating over $1 million in fees every day from trading across all its liquidity pools, not just those of Pump.fun tokens. That said, over 30% of Raydium’s daily trading volume comes from Pump.fun tokens, according to a Dune dashboard, meaning a good share of its fees could dry up if Pump.Fun switches away.

«100%, revenue hit is real,» InfraRAY said in a message to CoinDesk. But he cautioned that the market’s 30% haircut on RAY tokens was «overblown» and partially due to SOL’s own weakness.

He said any pivot to a new AMM could hit myriad issues: inadequate supporting infrastructure, low demand for migrated tokens, a flop on volume at launch.

«I think that’s a real risk they are overlooking but I could be wrong,» InfraRAY said.

Pump.Fun co-founder Alon Cohen declined to comment.

U.S. authorities have seized about $31 million in crypto tied to the 2021 hack of Uranium Finance, according to a Monday X post from the Southern District of New York (SDNY).

According to the post, the seizure was the result of a joint effort between SDNY and Homeland Security Investigations (HSI) in San Diego. A spokesperson for SDNY did not return CoinDesk’s request for comment before press time, and no further details about the seizure or any related investigation were immediately available.

Uranium Finance was essentially a clone of automated market maker (AMM) Uniswap deployed on Binance’s BNB chain (then called Binance Smart Chain). In April 2021, a hacker exploited a bug in Uranium’s pair contracts to steal $50 million in various tokens. At the time of the incident, the Uranium Finance hack was one of the largest monetary exploits in decentralized finance (DeFi) history.

After the exploit, the hacker attempted to launder a portion of the funds in a variety of ways, including using crypto mixer Tornado Cash, depositing small amounts of crypto into centralized exchanges, and, according to blockchain sleuth ZachXBT, perhaps through purchasing rare and highly valuable Magic: The Gathering trading cards.

Uranium Finance shuttered after the hack, leaving victims without answers or financial restitution. The partial recovery, which comes nearly four years after the initial attack, offers the first glimmer of hope for victims to see some of their money returned.
